Answer:

A=3

Step-by-step explanation:

24=-3(2a-15)-a

24=-6a+45-a

24=-7a+45

-45      -45

-21=-7a

-21/-7= 3

A=3

Answer: A = 3

Step-by-step explanation:

Simplify by multiplying

-6a + 45 -a

add like terms

-7a + 45 = 24

-7a = -21

a = 3

Samantha ran on a fitness track for 20 ​min, and then walked for 15 min. Her running rate was 230 ft per minute faster than her
Mnenie [13.5K]

Answer:

  560 ft/min

Step-by-step explanation:

Let r represent Samantha's running rate in feet per minute. Then r-230 is her walking rate. We can use the relation ...

   distance = speed × time

to write an equation for the total distance Samantha went.

  20r + 15(r -230) = 16150

  35r - 3450 = 16150 . . . . eliminate parentheses, collect terms

  35r = 19600 . . . . . . . . . . add 3450

  r = 560 . . . . . . . . . . . . . . divide by the coefficient of r

Samantha ran 560 feet per minute.

The graph of an absolute value function has a vertex of (2,3) and crosses the x-axis at (−1,0) and (5,0). What is the equation f
frez [133]

Answer:

Option D.

Step-by-step explanation:

The vertex form of an absolute function is

y=a|x-h|+k

where, a is a constant, (h,k) is vertex.

It is given that, vertex of an absolute function is (2,3). So, h=2 and k=3.

y=a|x-2|+3   ...(1)

It crosses the x-axis at (5,0). So put x=5 and y=0 to find the value of a.

0=a|5-2|+3

-3=3a

-1=a

Put a=-1 in (1).

y=(-1)|x-2|+3

y=-|x-2|+3

Now, put y=0, to find the equation for this absolute value function when y=0.

0=-|x-2|+3

Therefore, the correct option is D.

PLEASE HELP!
sesenic [268]

Answer:

36\sqrt{3}

Step-by-step explanation:

Hi!

Since an equilateral triangle means that every side is equal, our triangle will have 12 on all sides.

To find the height of an equilateral triangle we use \frac{a\sqrt{3}}{2}.

\frac{12\sqrt{3} }{2} = 6\sqrt{3}.

So the height is 6\sqrt{3}.

Now we have to solve 12 * 6\sqrt{3} ÷ 2.

12 \cdot 6\sqrt{3} = 72\sqrt{3}

72\sqrt{3}\: \div\: 2 = 36\sqrt{3}.

Thus, the area of the triangle is \boxed{36\sqrt{3}}.

Hope this helps!
